In the main.jsp file I use <tiles:insert> for "menu", "calendar", "survey", "greeting" and "main"

I'm still having trouble including a Struts action into a JSP (<c:import

I've tried using absolute URLs, passing the jsessionid to ensure that the session is not lost, but the request context is different between the JSP and the included action, so this not suitable for many situations. I've also tried upgrading to Struts 1.2.4. This does not resolve the "Response has already been committed" issue when including more than one Struts action in a JSP.
The app server is using JRE 1.4.1_03-b02.
Can anyone tell me whether they have seen this situation before? How common is it? Is it unusual to include Struts actions in JSPs? Anyone?
Thanks, Jeff

Subject: [****] Including a Struts action in a JSP -
IllegalStateException / truncated response issue
Hello,
I've seen a few posts on this subject, through this and other resources, but I haven't seen any appealing workarounds. I'd like to try to bring all the relevant information from these posts together and then ask for help in identifying a viable workaround. I apologize in advance if this issue is well known and understood and I just missed the best resources on the subject.
Goals:
1) To build a Struts application where _every_ request to the application goes through a Struts action that collects and packages data then forwards (using Struts ActionForward's) to a JSP.
2) To be able to include one or more Struts actions in any given JSP (ie: <c:import url="/someAction.do" />).
Behavior when implementing these goals:
1) Usually, when executing a single include of a Struts action on a JSP, everything works fine though sometimes there are problems (as listed below).
2) When including more than one Struts action on a JSP I get an IllegalStateException - Response has already been committed.
3) Sometimes, when a JSP only includes one Struts action, the first x bytes of the response will be missing when it is returned (without exception) to the client.
Relevant issues (correct me where I'm wrong):
1) Including (<jsp:include>, <c:import>, etc.) a JSP/Servlet on a JSP sometimes (always?) causes the response to be committed because includes use RequestDispatcher.include() which in turn commits the response.
2) Forwarding a request using an ActionForward from a Struts action to a JSP can not be done when a response has been committed.
3) Increasing the response buffer size has no effect on these issues.
4) Using the include directive (<%@ include file="filename" %>) won't work because that includes source a translation time.
5) It has been reported that using <tiles:insert> does not (fully/always?) resolve the problematic behavior.
6) Using absolute URLs with <c:import> prevents the response from being committed because the context of the request is assumed to be independent. The visibility of an authenticated, populated session can be affected by passing the jsessionid in on the URL. This seems to be the only viable workaround though I haven't tested it thoroughly yet.

My setup:
- Oracle AS 10g (OC4J) app server
- Struts 1.1
- JSTL 1.0.6
Is there any clean way to meet the two goals listed above without error?
Thanks,
Jeff
